[mythtv-users] Failed to open Hauppauge HVR-2250 TV card

Tue Jun 19 21:06:34 UTC 2012

Please, please help.

I just cannot get the MythTV backend to work.  I've configured my
capture card (Hauppauge HVR-2250).  This card is listed as supported.

I'm using MythBuntu 12.04 LTS that installs MythTV 0.25.

I've followed the steps recommended by RobotBeard.com "Getting a Haupauge
HVR-2250 to work with MythTV,", including installing his recommended
firmware in /lib/firmware:

  v4l-saa7164-1.0.3.fw
  v4l-saa7164-1.0.3-3.fw
  v4l-saa7164-1.0.2.fw
  dvb-fe-tda10048-1.0.fw

When the logs still complained about missing NXP7164-2010-03-10.1.fw, I
found it on the net and put it there too.  Rebooted.

Now lspci includes:

  03:00.0 Multimedia controller: Philips Semiconductors SAA7164 (rev 81)
  04:00.0 VGA compatible controller: NVIDIA Corporation GT218 [ION] (rev
    a2)
  04:00.1 Audio device: NVIDIA Corporation High Definition Audio
    Controller (rev a1)

It was recommended that I say that this card is DVB.  Note that it has
two tuners and RobotBreard.com recommends treating each one as a
separate card, which I have done.

Now when I do:

  ls -l lld /dev/dvb/*/*

I see:

  crw-rw----+ 1 root video 212, 1 Jun 15 00:17 /dev/dvb/adapter0/demux0
  crw-rw----+ 1 root video 212, 2 Jun 15 00:17 /dev/dvb/adapter0/dvr0

  crw-rw----+ 1 root video 212, 7 Jun 15 00:17 /dev/dvb/adapter1/net0

On the Capture card setup I specified each half as:

  [DVDB: /dev/dvb/adapter0/frontend0] (DVBinput)->(None)
and
  [DVDB: /dev/dvb/adapter1/frontend0] (DVBinput)->(None)

Note that I could not change the input from "None".  I suspect that this
may be my problem.

On Input conection I have:

  [DVB: /dev/dvb/adapter0/frontend0] (DVBInput)->(None)
and
  [DVB: /dev/dvb/adapter1/frontend0] (DVBInput)->(None)

On Profile Group I have

  Name: Profile 1
  Card-Type: DVB TV capture card (v3.x)

Yes, I have connected source to input:

  capture device: [DVB: /dev/dvb/adapter0/frontend0}
  Input:          DVInput
  Video source:   (None)  -- NOTE that I cannot change this from None;
                             could this be related to the problem?
and
  capture device: [DVB: /dev/dvb/adapter1/frontend0}
  Input:          DVInput
  Video source:   (None)  -- NOTE that I cannot change this from None;
                             could this be related to the problem?

For the catelog I set up the one for North America with a valid account
and password.

I manually started MySQL since MythBuntu apparently wasn't smart enough
to add it to /etc/rc5.d.

When I invoke mythbackend in foreground I the the following

Of course the frontend cannot connect to the backend because the backend
fails to start up normally.

Thanks for any help!!!
